33、gate shuts, and shall require at least two different deliberate manual actions to open the gate. 4.1.5 Connectors with a manual-locking gate, except screwlink connectors, shall require a deliberate manual action to lock the gate, and shall require at least two different deliberate manual actions to

34、open the gate. 4.1.6 Screwlink connectors shall require at least four complete rotations of the screw-motion gate from the fully screwed up position to disengagement of the threads. The threads shall not be visible when the gate is locked. 4.1.7 The gate opening a shall be determined as described in

38、nnectors) 4.4.1 Gate face After testing with a force of (1 0,02) kN in accordance with 5.4.1, the gate-locking feature of connectors shall still function correctly. Where the gate locking feature does not encircle the connector body, e.g. Figure 2b) and Figure 3, the gate-locking feature shall withs

39、tand a force of (1 0,02) kN without separating from the latch by more than 1 mm. 4.4.2 Gate side When tested in accordance with 5.4.2, connectors with a gate locking feature that does not encircle the connector body, e.g. Figure 2b) and Figure 3, shall withstand a force of (1,5 0,03) kN without any

40、partial fracture. After this test the gate-locking feature shall still function correctly. EN 362:2004 (E) 9 4.5 Corrosion resistance When tested in accordance with 5.5, connector gates shall still function in accordance with 4.1.4. Evidence of corrosion of the base metal is not acceptable. The pres

41、ence of tarnishing and white scaling is acceptable. NOTE Conformity to this requirement does not imply suitability for use in a marine environment. 4.6 Marking and information 4.6.1 Marking of connectors shall be in accordance with Clause 6. 4.6.2 Information shall be supplied with connectors in acc

42、ordance with Clause 7. 5 Test methods 5.1 Examination of design 5.1.1 General One sample may be used for these tests. Check that the connectors, in accordance with the definitions in Clause 3, meet the requirements of 4.1.1 to 4.1.7 by visual examination and simple check measurements. 5.1.2 Verifica

43、tion of the gate opening Verify the gate opening a by using a calibrated rod which has a diameter corresponding to the gate opening specified in the information supplied by the manufacturer, see Figure 5. Pass the rod through the gate opening and check that it allows the correct closure and locking

44、of the gate and free movement of the rod within the connector. 5.2 Static strength test 5.2.1 Apparatus The static strength test apparatus is a conventional tensile testing machine. The force measuring apparatus for static testing shall conform to EN 364:1992, 4.1.1.The rate of loading shall lie wit

45、hin the range of 50 mm/min to 200 mm/min if the connector contains a textile element subject to stress during the test; or 20 mm/min to 50 mm/min otherwise. 5.2.2 Preparation of test samples a) Test samples containing a textile element shall be conditioned in accordance with EN 20139 at the standard

46、 temperate atmosphere for testing and shall include the relevant pre-conditioning specified in Clause 3 of that document. The static strength tests can be performed outside the conditioning room, but the temperature shall be (23 5) C and the tests shall begin within 5 min of removal from conditionin

47、g. b) Test samples without a textile element may be tested without conditioning. c) Each test shall be carried out on a new sample. EN 362:2004 (E) 10 5.2.3 Method 5.2.3.1 Major axis testing Mount the connector in the tensile testing machine and apply the load by means of two bars with a radius of (

48、6 0,1) mm, which are arranged to be perpendicular to the major axis. It is important that the connector is free to locate itself on the bars at the start of the test and as the load is applied. The bars shall be well coated with molybdenum based grease where they come into contact with a metal part

49、of the test sample. If the connector is tested in a horizontal axis test machine, the connector shall be positioned in a vertical plane with the gate being the lower of the two major axis sides. If the connector is tested in a vertical axis test machine, apply a small force to the connector at right angles to the direction of loading to bias the gate away from the bars initially. The bias force shall be approximately equal to the gravitational weight of the connector. Apply the required minimum force in accordance with Table 1 or in acc
